CLAMPING-RING.

Specification of Letters Patent.

Patented Dec. 8, 1907.

' To all whom it may concern:

I bodying my invention and said invention is fully disclosed in thefollowing description and claims.

The object of my invention is to provide a clamping ring for pipecouplings, constructed of wrought metal such as wrought iron or steelwhich shall provide an annular plate portion disposed perpendicularly tothe axis of the ring, and provided with bolt holes, and having its innermarginal portions bent at an angle thereto to form an annular flangeportion, the outer edge of said flange portion being bent inwardly,substantially parallel to the plate portion to form a packing recess andto provide a circular aperture for the passage of a pipe sectiontherethrough.

In the drawings, Figure 1 represents an elevation of a clamping ringembodying my invention. Fig. 2 represents a sectional view of the same,and Fig. 3 is a plan view of the same.

The herein described clamping ring is formed in one piece and isconveniently formed by forging or stamping the same from sheet metal,such steel, although it may be formed in other ways if desired.

A represents the annularflat plate portion of the ring disposedsubstantially perpendicularly to the axis of the ring and provided atsuitable intervals with bolt holes a of any as Wrought iron or' desiredsize or shape. The inner marginal portions of the plate portion are bentat an angle thereto (and preferably perpendicularly) on one side, asindicated at a to form an annular flange portion at the inner edge ofsaid plate portion, the outer edges of which flange portion are bentinward as at a substantially parallel to the plate portion A. The edgeof the inwardly extending annular portions a forms a circular pipeaperture a for the passage of a pipe section (shown in dotted lines inFig. 2) therethrough, and said inwardly bent portions a also form anannular packing recess a, for the reception of an annular packing ring(not shown) which will lie between the flange portion a and the pipesection, as will be readily understood, the inwardly extending portions(1 forming the bottom of said packing recess. The inner diameter of theplate portion a is obviously considerably greater than that of the pipeaperture a as shown.

What I claim and desire to secure by Letters Patent is A clamping ringfor pipe couplings formed in one piece from wrought metal, and having anannular plate portion disposed substantially perpendicularly to the axisof said ring and provided with bolt holes, an annular flange portionextending from the inner edge of said plate portion substantiallyperpendicularly thereto and on one side of the same, and having at itsouter end an inwardly extending annular flange substantially parallelwith said plate portion forming a packing recess, and roviding a centralpipe aperture, the inner 'ameter of said plate portion being greaterthan that of the said pipe aperture, substantially as described.

In testimony whereof I aflix my signature, in the presence of twowitnesses.

JAMES CLARK.
